MailAdx

Most newsletter ad networks were built for display web, then awkwardly retrofitted for email. MailAdx is built from the ground up for newsletters — no cookies, no tracking pixels that break in inboxes, just real-time bidding (RTB) that matches your sends with relevant advertisers automatically. If you run a newsletter, MailAdx plugs into your existing send flow, auto-inserts ad placements, and lets demand bid for your inventory in real time — so you earn more per send without chasing sponsors.
